Procedure 1
Check if the input of the over limit switches connected to the servo amplifier is loaded to FP7
MC Unit by operating them forcibly.
Points to check
Check if the limit setting is enabled, input logic is correct in the parameter setting menu of CMI.
Procedure 2
Check if the limit stop is activated at the time of limit input by the tool operation function of
CMI or performing the JOG operation with a program.
Procedure 3
Using the JOG operation, check if the over limit switch is functioning properly.
